Summary Information

The Federal Highway Administration (FHWA) conducted a study to explore the potential benefits and costs of fully deploying ITS operational strategies in large, medium, and small metropolitan areas. ITS deployment and operations were modeled for Seattle, Cincinnati, and Tucson, respectively. The strategies developed for Seattle and Cincinnati were based on 2003 traffic conditions while those for Tucson were based on traffic conditions forecast for 2025. The analysis considered a 25 year period, and the annual costs to implement, operate, and maintain each system were adjusted to 2003 dollars. This summary report presents the costs of the Tucson ITS full deployment scenario.

ITS Strategies

Extracted from Table 1 in the source report, the details of the ITS strategies for the Tucson full-deployment scenario are presented below.

System Costs

The table below, extracted from the source report (Table 3), shows the annual average life–cycle costs required to implement, operate, and maintain the ITS strategies identified above. The estimated annual cost was $72.1 million for the full ITS deployment and operations in the Tucson metropolitan area.

Public sector costs

The public sector was expected to fund 72.6 percent of the ITS strategies and the private sector 27.4 percent. The private sector funds were to be used to equip the commercial trucks to enable automated screening and clearance of the trucks at check stations.

One of the strategies identified was emergency management systems. Deployment data included the number of emergency vehicles and ambulances equipped with control service, automated vehicle location (AVL), and telemedicine. At full deployment, 1340 emergency vehicles and 130 ambulances were estimated to be equipped with ITS devices. The annualized life-cycle costs of emergency management systems for Tucson were estimated at $2.1 million.
